* @param fileName full file name of recording (/media/USB-... or /ram/media/USB-...)
* @param startTime recording start time
* UTC time in "YYYYMMDDThhmmss" format or number of seconds since Epoch (1970/01/01 UTC)

* @param endTime recording end time
* UTC time in "YYYYMMDDThhmmss" format or number of seconds since Epoch (1970/01/01 UTC)

* @example
* // number of seconds since Epoch can be obtained via Date object
* var date = new Date();
* var startTime = date.getTime()/1000;
